Another liner for cast-in-place or potted installation, used to hold Slip/Fixed Reneable drill bushings. Unlike diamond-knurl uniock liners, EZ-cast linres hold either the "slip" or "fixed" side of a Slip/Fixed Bushing, since they include an integral lockscrew holder. Diamond-knuelws OD provides superior holding strength against both rotational and axial forces. Since the bushing's OD is not ground, keep the ID accurately located during casting or potting to ensure accuracy in the finished tool.
